Low fps problem with windows xp
I've made a opengl game, ran it on pentium III, windows 2000/98 without video card, FPS = 75. But when I ran it on windows XP without video card, FPS = 4!
So I decided to do bench marking, I picked up a simple triangle with FPS counter from this solid site
In win2000/98 = 150 fps, in winxp = 73 fps.
How do I deal with this slowness problem? Is there any win32 api code changes I need to make(my windows/opengl code is similiar to Digiben's) in order to adapt to windows xp? Or should I just tell the windows xp users to get a video card???
Re: Low fps problem with windows xp
What you mean "without video card"? Try to disable vertical sync in driver setup pages. Try to install new drivers on XP machine. Can you post machine specification?
